In the same period in 2016, the Company reported a loss from continuing operations of $0.5 million, or a loss of $0.01 per diluted share, and in the first quarter of 2017 reported income from continuing operations of $4.4 million, or $0.07 earnings per diluted share. The average realized price for crude oil in the second quarter of 2017 was $46.83 per barrel, up 15% from $40.79 per barrel in the second quarter of 2016. In the first quarter of 2017, the average realized price for crude oil was $51.99 per barrel. Adjusted EBITDAX totaled $8.6 million in the second quarter of 2017 compared with $7.7 million in the same period of 2016, and $10.4 million in the first quarter of 2017.

Adjusted EBITDAX is a Non-GAAP financial measure and is described and reconciled to net income (loss) in the attached table under “Non-GAAP Financial Measures.”

Cary Bounds, VAALCO’s Chief Executive Officer commented: “We remain focused on delivering strong operational and financial results, and I am pleased with our second quarter earnings. We reported earnings per share of $0.04, generated strong operating results and production rates came in at the high end of our guidance range. Our focus in 2017 is to maximize margins through operational excellence and execute on our corporate strategy. As we look to the future, we remain confident in the development opportunities on our offshore Gabon asset, and we are seeking similar growth opportunities in West Africa, where we can leverage our strong operational and technical expertise.”

Gabon and Equatorial Guinea

In the second quarter of 2017, production decreased to 4,363 BOPD compared with 4,622 BOPD in the first quarter of 2017 primarily due to natural decline.

On July 18, the electrical submersible pump (ESP) in the South Tchibala 2-H well failed, resulting in the well being temporarily shut-in. The well was producing approximately 1,300 barrels of oil per day gross, or 350 barrels of oil net to the Company, prior to being shut-in. VAALCO is working to mobilize a hydraulic workover unit to move onto the Avouma platform and replace the ESP system in the well, which is expected to be back on production by the fourth quarter 2017. The Company successfully utilized a hydraulic workover unit to replace the ESP in the well late last year at a significantly lower cost rather than mobilizing a jackup rig. As a result of recent diagnostic work, the Company believes it has determined the cause of the 2016 ESP failures in this well, and a newly designed pair of ESPs will be installed in the South Tchibala 2-H well during the upcoming workover operation. VAALCO is currently evaluating performing one to two additional workovers in conjunction with the South Tchibala 2-H workover to replace the ESPs.

During July 2017, VAALCO completed its planned 2017 maintenance turnaround for the Etame Marin FPSO and four platforms. The entire work scope was successfully completed with no environmental or safety issues. The field was shut-in for nine days during the turnaround and is now back on production. The results of the maintenance and inspection work confirmed the Company’s asset integrity programs continue to be effective. The next turnaround will be in 2018.

The Company continues to examine alternative, lower cost development options for discoveries in the Mutamba Iroru permit onshore Gabon, and in Block P offshore Equatorial Guinea. These discoveries present unique development opportunities that will be re-evaluated as prices continue to recover.

Discontinued Operations – Angola

The small loss of $0.2 million from discontinued operations for this quarter related to ongoing administrative costs. In the second quarter of 2016, there was a minimal loss of $20 thousand from discontinued operations, or $0.00 loss per diluted share. Since September 2016, the Company has reflected an accrual of $15.0 million for a potential payment which represents what VAALCO believes to be the maximum potential amount attributable to VAALCO Angola’s interest under the Block 5 PSA. The Company is in active discussions with representatives from Sonangol E.P. regarding this potential payment and other possible solutions and believe that the ultimate amount paid will be substantially less than the accrued amount.

Sale of U.S. Properties

On October 17, 2016, the Company signed a letter of intent to sell its entire acreage interests in the East Poplar Unit in Montana for $250,000 and the assumption of asset retirement obligations. The transaction closed on April 3, 2017.

2017 Second Quarter Financial Results

Total oil and natural gas sales for the second quarter of 2017 were $20.4 million, compared to $18.8 million for the same period in 2016, and $21.3 million in the first quarter of 2017. During the second quarter of 2017, VAALCO sold approximately 414,000 net barrels of oil at an average price of $46.83 per barrel, compared to 436,000 net barrels at an average price of $40.79 per barrel in the second quarter of 2016. Second quarter 2017 revenue was positively impacted by the increase in realized pricing which was offset in part by a decrease in sales volumes compared to the same period in 2016.

Costs and Expenses

Total production expense, excluding workovers, was $9.7 million, or $23.41 per barrel of oil equivalent (BOE) of sales, in the second quarter of 2017, compared to $8.0 million, or $18.16 per BOE of sales, in the second quarter of 2016, and $8.1 million, or $20.44 per BOE of sales in the first quarter of 2017. The second quarter of 2017 costs, excluding workovers, were higher than the second quarter of 2016 primarily due to VAALCO’s increased ownership interest as a result of the November 2016 Sojitz acquisition, costs associated with certain regulatory requirements and FPSO cost escalation.

Depreciation, depletion and amortization (DD&A) expense was $2.0 million, or $4.76 per BOE of sales in the three months ended June 30, 2017 compared to $1.9 million, or $4.39 per BOE in the comparable period in 2016, and $1.9 million, or $4.74 per BOE in the first quarter of 2017.

General and administrative (G&A) expense for the three months ended June 30, 2017 was $3.0 million, or $7.36 per BOE, as compared to $4.0 million, or $9.06 per BOE in the three months ended June 2016, and $3.1 million, or $7.94 per BOE in the first quarter of 2017. General and administrative expense includes $0.6 million, $1.0 million, and $0.2 million of non-cash compensation expense for the quarters ended June 30, 2017, June 30, 2016, and March 31, 2017.

Income tax expense for the second quarter of 2017 was $3.1 million compared to $3.0 million for the same period in 2016, and $3.2 million in the first quarter of 2017. The increase in tax compared to the same period a year ago is primarily attributable to higher revenues from the Company’s operations in Gabon.

Hedging

In order to limit VAALCO’s commodity price risk, in 2016 the Company purchased crude oil puts for part of its 2017 volume. As of June 30, 2017, VAALCO had unexpired crude oil put contracts covering 360,000 barrels of anticipated sales volumes for the period from July 2017 through December 31, 2017 at a weighted average price of $50.00. The Company recorded a non-cash mark-to-market gain of $0.1 million related to the puts during the second quarter of 2017 which was included in “Other, net” in the Condensed Consolidated Statements of Operations. The Company has not entered into additional derivative contracts since June 30, 2017.

Capital Investments/Balance Sheet

During the three months ended June 30, 2017, VAALCO invested approximately $0.3 million in capital expenditures on a cash basis, primarily for equipment and enhancements. The Company has no material commitments for capital expenditures for the balance of 2017.

At the end of the second quarter, VAALCO had an unrestricted cash balance of $20.6 million. This does not include an additional $0.8 million in restricted cash (related primarily to deposits in Gabon) classified as current assets or the additional $0.9 million of restricted cash classified as long term.

At June 30, 2017, debt, net of deferred financing costs, totaled $13.0 million, of which $8.3 million was classified as current, reflecting the repayment terms of the loan agreement with the IFC.

NON-GAAP FINANCIAL MEASURES

Adjusted EBITDAX is a supplemental non-GAAP financial measure used by VAALCO’s management and by external users of the Company’s financial statements, such as industry analysts, lenders, rating agencies, investors and others who follow the industry as an indicator of the Company’s ability to internally fund exploration and development activities and to service or incur additional debt. Adjusted EBITDAX is a non-GAAP financial measure and as used herein represents net income before discontinued operations, interest income (expense) net, income tax expense, depletion, depreciation and amortization, impairment of proved properties, exploration expense, non-cash and other items including stock compensation expense and commodity derivative loss.

Adjusted EBITDAX has significant limitations, including that it does not reflect the Company’s cash requirements for capital expenditures, contractual commitments, working capital or debt service. Adjusted EBITDAX should not be considered as a substitute for net income (loss), operating income (loss), cash flows from operating activities or any other measure of financial performance or liquidity presented in accordance with GAAP. Adjusted EBITDAX excludes some, but not all, items that affect net income (loss) and operating income (loss) and these measures may vary among other companies. Therefore, the Company’s Adjusted EBITDAX may not be comparable to similarly titled measures used by other companies.
